Poor prepregnancy cardiovascular health is associated with a higher risk of developing gestational diabetes and coronary artery calcium in midlife, according to a recent Northwestern Medicine study published in JAMA Cardiology.

An EHU study analyzing different genetic markers associated with facial features of the European population has shown a strong link between 10 of these markers and the facial morphology of people from the Iberian Peninsula. The researcher Belén Navarro, the author of the study, highlights the importance of carrying out research in specific populations to obtain prediction models that can be used to reconstruct a person's face using DNA samples. The study is published in the journal Scientific Reports.

Stressful life events can negatively impact brain health. Specifically, grief over the loss of a partner has been linked to alterations in biological processes associated with Alzheimer's disease, while unemployment and financial loss have been associated with structural differences in the brain.

New research has shown how boys being overweight in early childhood or having chickenpox or another infectious disease in infancy may increase their risk of having chronic disease in later life.

A new study led by researchers at the University of Toronto reveals that boys and men who perceive anabolic-androgenic steroid (AAS) use within their social circles are more likely to report intentions to use these substances themselves, even if they have never used them before.

As the fall sports season approaches, athletes and their families may be concerned about the potential risk of head injuries. Now, they can take comfort in the findings of a clinical study done on the long-term outcomes of concussion patients.

In 1954, the world's first successful organ transplant took place at Brigham and Women's Hospital, in the form of a kidney donated from one twin to the other. At the time, a group of doctors and scientists had correctly theorized that the recipient's antibodies were unlikely to reject an organ from an identical twin.

A new Burnet study has examined how probiotics could potentially treat gut-related conditions in pregnant women.

Nutrition scientists have been working to understand the relationship between type 2 diabetes and genes that express a salivary enzyme that breaks down starch, but many conflicting studies have led to few clear answers.

Given the rising rates of childhood obesity and its association with multiple chronic diseases, a team of Children's Hospital Los Angeles researchers examined the relationships between financial adversity, changes in the brain, and weight gain in adolescents. Economic hardship has been associated with changes in subcortical neurodevelopment and the risk of developing obesity, but studies have yet to illuminate how these different factors interact, and in what sequence.

For the first time, an international research team has developed concrete, evidence-based stretching recommendations for practical use. The team was led by Prof. Dr. Dr. Jan Wilke of the University of Bayreuth.
